background common carotid artery (cca) ultrasound with measurement of intima-media thickness (imt) is a safe and noninvasive technique for assessing subclinical atherosclerosis and determining cardiovascular risks. moreover, the pattern of wall thickening in the brachial artery (ba) is rather diffuse compared to the carotid artery and may be a more sensitive indicator of long-term systemic expo...

This paper addresses the problem of determining suitable mask values and sizes for the discrete implementation of the Laplacian of Gaussian edge operator. This is achieved by providing a theoretical connection between the mask size and the edge detection error introduced by truncation of the operator. Additionally, the importance of introducing a bias correction within the finite approximation ...

quality inspection is an indispensable part of modern industrial manufacturing. steel as a major industry requires constant surveillance and supervision through its various stages of production. continuous casting is a critical step in the steel manufacturing process in which molten steel is solidified into a semi-finished product called slab. once the slab is released from the casting unit, th...

background: to reduce uncertainties of patient positioning, the computerized tomography (ct) images acquired at the treatment planning time can be compared with those images obtained during radiation dose delivery. this can be followed during dose delivery procedure as image guided radiotherapy (igrt) to verify the prescribed radiation dose delivery to the target as well as to monitor radiation...

In this paper a symmetry based face detection technique is proposed. Here symmetry of the human face is used to quickly locate the human faces from an image. At first sobel edge detection operator is applied to get the edge image from the original image. In order to measure total number of symmetrical points present in an image window, a newly proposed point symmetry based distance is used. Kd-...

Skin cancer has been the most usual and illustrates 50% of all new cancers detected each year. If they detected at an early stage, treatment can become simple and economically. Accurate skin lesion segmentation is important in automated early skin cancer detection and diagnosis systems. The aim of this study is to provide an effective approach to detect the skin lesion border on a purposed imag...

In this contribution we introduce a method for the automatic detection of facial features and characteristic anatomical keypoints. In the application we are aiming at the anatomical landmarks are used to accurately measure facial features. Our approach is essentially based on a selective search and sequential tracking of characteristic edge and line structures of the facial object to be searche...

Visual features act as an important part for hand pre-shaping during human grasp. This paper focuses on using visual features in an image to predict successful grasp types, which can be used in the robot grasp manipulation. The following questions are discussed: First, how to recognize different shapes in a given image. Second, how to train the system using image-grasp pairs. Third, evaluate th...

The automatic detection of runway hazards from a moving platform under poor visibility conditions is a multifaceted problem. The general approach that we use relies on looking at several frames of the video imagery to determine the presence of objects. Since the platform is in motion during the acquisition of these frames, the first step in the process is to correct for platform motion. Extract...
